Intercom interview questions

It initially took 2 weeks to schedule a meeting with the talent person, but they were then quick to follow up with the problem solving interview. The interviewer acted more as an observer rather than a peer and he was not particularly confident about Java as a language. I solved the problem, but was unable to test the solution in the given time because of a misplaced parenthesis on Java comparators. I didn't spot the mistake by the end and neither did the interviewer. I think this is the reason for the rejection, but I can't be 100% sure since they didn't provide any feedback.

After the initial screening with recruiter to scout for relevant experience, you'll be asked to live code a Hakkerrank Load Balanced Assignment: Populate agents with given names, Create a function to change the limit of conversations for an agent (treat only the case current load lower than given limit, return false otherwise) Create a function to assign a set of conversations to available agents. Agents assigned by the least busy, and on a tie pick the one that waited the most. I've managed to complete all the requirements and I was told my solution was "neat". One week after I've received a rejection email saying that they can offer feedback if I wanted to. I've replied yes please, but from that moment I got ghosted by the recruiter.
